It is the general object of our invention to provide a new constructionof shoe. or slipper, in which the upper, insole and out-sole are securedtogether in a new and improved manner.

A further object is to provide an improved method of making the shoe andassembling and securing the parts thereof together, by the use of whichmethod marked economy of manufacture is attained. The shoe or slipperthus constructed is of attractive appearance and possesses excellentwearing qualities.

Our invention further relates to arrangements and combinations of partswhich will be hereinafter described and more particularly pointed out inthe appended claims.

Preferred forms of the invention are shown in the drawings, in whichFig. 1 is a side elevation of a special last used in carrying out ourinvention;

Referring to the'drawings, our improved method of making a shoe orslipper involves the use of a 15 special or preliminary last L, shown indetail in Figs. 1, 2, 3 and 24. v

This special last L comprises an upper part or body portion 25 ofstandard shape and commonly made of hard wood. A metal plate 23 isperma- 20 nently secured to the bottom of the last and extends beyondthe edges of the last, thus providing a flange portion or projection 21.This flange may extend entirely around the last as shown at 21. in Fig.24 or may be confined to the front and shank portion as indicated at 21in Fig. 3. This metal plate 26 or 28' is provided with the usualopenings 23 through which the insole member may be tacked to the last.

In making a shoe by our improved method. we first take an oversizeinsole 30 (Fig. 4) of any suitable material, such as fibre board. Thismaterial should be relatively thin but of substan-.* tial stiffness.Before assembling the insole 33 on the last L or L, we apply a coatingof a suitable cement around the edge of the insole on the bottom facethereof, as-indicated at 3| in Fig. 4.

We then secure the insole 30 to the bottom of the last by tacks 32(Figs. 5 and 7) it being essential that the insole shall be of the exactoutline of the metal plate 23 and that the edge of the insole shallcoincide with the edge of the plate.

We next assemble the upper 33 on the last L, bringing the edge portion34 of. the upper around the edge of the last plate 26 and insole 33, andpressingit firmly against the cemented portion 3| of the bottom of theinsole. -Preferably the edge portion of the upper is given a cementcoating before the parts are assembled.

We then remove the tacks 32 and draw the special last L out of thepartially assembled shoe, leaving the upper 33 and insole 30 in theassembled relation shown in Fig. 8.

We then insert a row of stitching 36 (Figs. 9 55 and 10) around the edgeof the insole and up-' per, thus binding the doubled edge portion of theupper 33 around the edge portion of the insole 30 and securing it atboth faces of said insole.

During this stitching operation, we may, if destitchesextendingthrmmhtheom-soietheedze tionottheshocinth'eusuaimannenremovethelastn'omtheshoelndlmt heelflmgifli'Prlortonssunhlingtheout-soleflontheraho, thecndportionsll (Fig.1?)otthebinderflare turnedinwlrdovertheheel portionotthemsole.soastoproducen"flnishedei!ectitthe" recr'ot the shank, as indicated at 44(Flam-i7 andlfl).
